Overview

RtMidi is a set of C++ classes which provides a concise and simple, cross-platform API (Application Programming Interface) for realtime MIDI input / output across Linux (ALSA & JACK), macOS / OS X (CoreMIDI & JACK), and Windows (MultiMedia Library) operating systems.

python-rtmidi is a Python binding for RtMidi implemented using Cython and provides a thin wrapper around the RtMidi C++ interface. The API is basically the same as the C++ one but with the naming scheme of classes, methods and parameters adapted to the Python PEP-8 conventions and requirements of the Python package naming structure. python-rtmidi supports Python 2 (tested with Python 2.7) and Python 3 (3.4, 3.5, 3.6 and 3.7).

Usage example

Here’s a quick example of how to use python-rtmidi to open the first available MIDI output port and send a middle C note on MIDI channel 1:

import time
import rtmidi

midiout = rtmidi.MidiOut()
available_ports = midiout.get_ports()

if available_ports:
    midiout.open_port(0)
else:
    midiout.open_virtual_port("My virtual output")

note_on = [0x90, 60, 112] # channel 1, middle C, velocity 112
note_off = [0x80, 60, 0]
midiout.send_message(note_on)
time.sleep(0.5)
midiout.send_message(note_off)

del midiout

More usage examples can be found in the examples and tests directories of the source repository.
